I have raise 5 children and my siblings and I all had quilts fromthe get go and we are all here. I have never heard of it either until my son and his wife just had a baby and they asked if I would wait till he was a few months old to make his so that it does not hurt him so I quit making the quilt until later. Noq I have 5 s I may just give themall away..Who knows. There are rules for rules and pills for pills .....it all get old to me????
